Connecting the Reamer and Product
WARNING
If the drill rotates or extends while you or others are
manually working on the drill bit or pipe in front of
the machine, the worker could get caught in the bit
or pipe causing serious injury, amputation, or death.
• Enable the exit-side lockout on the
exit-side-lockout transmitter before approaching
the dill bit or pipe when attached to the machine.
This will disable the drill carriage.
• Do not wear loose clothing or jewelry when
working on a drill bit or pipe attached to the
machine. Tie long hair up and out of the way.
1. Using the exit-side-lockout transmitter, enable the exit
side lockout.
2. Remove the drill head from the lead bar.
3. Double check the reamer to ensure that the fluid ports
are clean and free from obstructions.
4. Install the reamer and swivel onto the end of the lead
bar as directed by the reamer manufacturer
5. Connect the product to the reamer using an appropriate
pulling connection; refer to your Authorized Toro
Dealer to acquire the appropriate puller to meet your
requirements.
Removing Drill Pipes
1. Using the exit-side-lockout transmitter, enable the exit
side lockout.
2. Install a drill-pipe wiper around the pipe and into the
retaining bracket on the front of the machine.
This will remove most of the dirt and mud from the
pipe as you pull it back into the machine, keeping the
machine clean. Contact your Authorized Toro Dealer
to purchase drill-pipe wipers.
1. Drill-pipe wiper
3. Disengage the exit-side lockout and reset the system.
4. Begin rotating the drill spindle clockwise and slowly
retract the drill carriage to pull the pipe back into the
machine
5. When the joint between the pipes is centered between
the two wrenches, the drill carriage will stop, and a
green light will illuminate below the spray valve.
6. Close the lower wrench onto the pipe joint.
Note: The drilling fluid will automatically shut off
when you close the lower wrench.
7. Rotate the pipe gripper to the drill frame, extend the
pipe-gripper arms to the pipe, and grip the pipe to
support it.
8. Close the upper wrench onto the pipe joint.
9. Rotate the upper wrench counterclockwise until the
joint is loosened.
10. Release the upper wrench.
11. Pull back the carriage approximately 12.7 mm (0.5
inch).
Note: This will allow the carriage to float, and will not
damage the pipe threads.
12. Rotate the drill spindle counterclockwise moving
rearward slowly until the pipes are separated.
13. Move the drill carriage back until the male-pipe threads
just clear the female end of the lower pipe, then close
the upper wrench onto the pipe end, but not on the
threads.
14. Rotate the drill spindle counterclockwise until the
upper-pipe joint is loose but not separated.
15. Release the upper wrench.
16. Move the drill carriage back until the pipe is lined up
with the pipe holder.
